The echocardiographic parameters were followed for 3 years in 15 boys aged 13 years on average, who were beginning competitive canoe race training, and were compared with the corresponding data on 17 boys of the same age who did not take part in sports. As compared to non-sporting boys the 13-year-old canoeist boys had a larger left ventricular(More)
Dipyridamole and dobutamine stress were performed in the same 41 angiographically controlled patients. Both tests were followed by 2 dimensional-echocardiography. The dose of dipyridamole was 0.56 mg/kg/4 min. or 0.84 mg/kg over 10 min., while the dose of dobutamine was 10-20-30-40 and 40 micrograms/kg/min. over 3 min. each step. In addition, to reach the(More)
The diagnostic value of the dipyridamole echocardiography test was investigated in 46 patients who underwent coronary angiography due to suspected ischaemic heart disease. Twenty-two of 46 patients were found to have a narrowing of at least 70% one vessel. Twenty-four hour ECG monitoring was also performed on 19 patients on the day of the dipyridamole test.(More)
The authors studied with 99m-Tc Cardiolite (methoxy-isobutyl-isonitrile) SPECT examination the effect of coronary bypass operation on the myocardial perfusion. One week before and 3 weeks after the operation examinations were performed first with dipyridamol loading and 24 hours later in rest. The regional perfusion of the myocardium was studied on the(More)
The clinical performance of the planar vs. tomographic ergometric stress 201-Tl myocard perfusion scintigraphy was compared. The results of the investigations of 80 patients were analysed retrospectively. In 59 patients planar, in 21 tomographic imaging was performed. As a consequence of clinical decision making cardiac catheterization was made in all of(More)
Echocardiographic data on 21 top-grade kayak- canoeists and 16 top-grade handball players are compared. While the end-diastolic and end-systolic diameters as well as end-diastolic and end-systolic volumes did not appreciably differ, the posterior wall and particularly the interventricular septum both in diastole and systole were significantly thicker in(More)
Hemocoagulation system state and plasmatic fibronectin level at experimental associated craniocerebral trauma have been studied at 29 mongrel white rats (males). It has been revealed that associated craniocerebral trauma, complicated by disseminated intravascular blood coagulation, is accompanied by reliable decrease of plasmatic fibronectin concentration.(More)
The authors have examined supposed causes of positive Th-201 stress scintigraphy. Patients were divided into two groups according to the presence of exercise-induced transitory hypoperfusion or in absence of it. In both groups negative coronarograms were verified. Results of two groups were compared according to parameters of the left ventricle function,(More)
Twenty-two patients with single-vessel left anterior descending coronary artery disease were investigated by means of dipyridamole stress thallium-201 myocardial perfusion scintigraphy, using single photon emission tomography (SPET), 1 week before and 2-5 weeks after coronary bypass surgery. The dose of dipyridamole was 0.56 mg/kg, and the injected activity(More)
